CLAY PRESS.

Application filed necemt'ei?, 1924.` serial No. 756,442.

.To all whom 'it may concern: i y

Be it known that I, PAUL F. LoIcHor, a citizen ot' the United States,residing at Canton, in the county of Sta-rk and State of" Ohio, haveinvented certain `new and `useful Improvements in Clay 'Presses,of whichthe following is a specification.

Thisinfvention relates to clay presses used i in the stilimud processofmaking brick or tile forforcing the clay through a die of properconfori'na'tion in a column which is received upon a cut-olil table `ofusualconstruction to be severed -into brick or tile of the desired sizeinpcustomary manner. The common form of clay presssuch as is in generaluse, comprises an auger longi tudinally aligned withthe die for,forcingVthe clay in a column "through thedie. The clay beingV carried aroundspirally by the auger forms laminations in` the column which are greatlyaggravated in certain kinds of clay'or shale.

Thus each brick or tile cut from fthe` column has these lamlinationsrunning through its structure, weakening the bri'cltor` tile 'and:frequently causingfthe sameft crack or break around the line'of the.laminations This is especially objectionable where it is desired to cuta `brick `in two as instead of" getting a square face, the brick will`follow the lines of the laminations in breaking.

It is `known that attempts have been Vmade to eliminate theselaminations in the clay column by providing a plurality otrollers forforcing the claythrough the die, but it has been found byeXperience'that the roller press will not `properly force the claythrough the dies in `a column of `the proper quality and constituency,theV back pressure against the rollers beingV greater' kthan the forwardpressure' of 'the rollers` upon the. clay, frequently causingthe-clay`to work its way around the bearings of the rollers;

The objectot` the present invention isto` provide a clay press `whicheliminatesthe` laminat-ions inthe column produced inthe usual clay augerand at thesame time .over-` comes the objections tothe roller pressabove referred to.

The above 'and other objects may be attained by providing a pair ofrollers behind forcin'gthe clay through the salme, the auger beingpreferably located at right angles to the axis of the die, whereby anylaminations formed in the clay by the auger are eliminated by therollers.`

An embodiment or' the invention is illustrated in the accompanyingdrawings, in which* Figure 1 is a longitudinal, vertical, seotional viewthrough the improved clay press.;

Fig. 5, a rearelevation of the press; and

Fig. 6, a front elevation of the same, a portion of the die being brokenaway.

Similar numerals refer to similar parts throughout the drawings.

The press is located in 'a housing comprising the side plates l spacedby the upper and lower curved plates 2 and 3, respectively, which areconnected thereto as by the screws 4. y

The die 5, which may be of lusual and well known construction,isjconnected tothe forward projections G ofthe upper and lower plates 2and 3` as by the screws 7 and the usual cut-ori' table indicated at 8may be provided adjacentto the die to receive the clay column as itpasses from the same.

The upper and lower rolls 9 `and 10 respectively are fixed upon theshafts ll and 12 respectively, which are journaled in the bearings 13 inthe side walls of the housing. Each of these rolls is preferablyprovided with a corrugated periphery as illustrated, and `is provided ateach end witha neck 14 journaled in abearing `socket 15 inthe adjacentside wall.

`As shown in Fig. l, the rolls 9 and 10 have a very slight clearancewithin the upper and lower plates Zand 3. As illustrated in this figure,theforward"projections vand 4, a section Aon the line l4, Fig. l

rear projections 7a of the upper and lower plates terminate near thepinch of the rolls, the opposite faces of the forward projections beingslightly flared away from the rolls, as shown at 15a, while the oppositefaces 16 of the rear projections are preferably parallel.

The auger housing 17 is vertically disposed and provided with theinclined downwardly tapered passage 18 communicating with the reducedpassagelf leading to the rolls. The auger 19 is provided with thedepending shaft 20 journaled in the bearing 21 provided at the lower endof the auger housing, a bevel gear 22 being fixed to the lower end ofsaid shaft and meshing with the bevel pinion 23 upon the drive shaft 2A.

The upper end of the auger housing is flared, forming a hopper 25 andthe enlarged wing 26 is preferably provided upon the upper end of theauger shaft working in the mouth of the hopper for conveying the claydown to the double screw of the auger.

A pinion 27 is mounted upon the drive. shaft 24 and meshes with thelarge gear 28 upon one end of the shaft 12, a smaller gear 29 upon theother end of said shaft, meshing with a similar gear 30 upon the shaft1l.

The gear is so constructed that the clay will be fed downward by theauger to the rolls at a speed just sufficient to permit the rolls toforce the clay through the die at the proper rate of speed to produce aclay column adaptable for forming brick or tile.

The auger being located at right angles to the axis of the die and alsoat right angles to a plane passi-ng through the anis of each roll,pre-vents the formation of any laminations in the clay column, as anylaminations formed by the vertical auger are eliminated by the rolls.

By providing a sliding fit between the ends of the rolls and the sideplates 1 andv by forming the necks 1A upon the Vrolls journaled in thebearings 15 in the side plates, clay is prevented from working bctweenthe plates and rolls and into the-journals of the rolls.

ln order to prevent any leakage of clay around the rolls and into thebearings, a plurality of grease cups 31 is provided around the bearingsand ends of the rollers for the reception of a grease gun, by means ofwhich grease may be maintained at high pressure around these parts.
